Ahoj,
bylo by mozne zde uvest co je pravdepodobne zdrojem vibraci dle frekvencniho analyzatoru.
Napr. 160Hz ... xxx, 240Hz ... xxx, atd

Pokud tocis priblizne 2150RPM, pak je 160Hz spicka pochazejici od vrtulky a 240Hz zase od motoru.
Bohuzel to nelze nikdy s jistotou rici, protoze kazda heli ma tyto spicky odlisne a muze jich mit nekolik.
Staci vedet, ze prevodovy pomer vrtulky je priblizne 4.5.
160 * 60 = otacky vrtulky.
Otacky vrtulky / 4.5 = otacky hl. rotoru.

Asi jsem úplný pako, ale rejdím myší po celém okně a otáčky nikde. Poradte mi po lopatě. :shock: Najetí myší na co?
